Description

The The present invention relates to new cosmetic compositions for topical use, especially for sun protection of the skin and / or the hair are intended against UV radiation (compositions, hereinafter simply referred to as sunscreens) and their use in the cosmetic application mentioned above. It concerns more precisely sunscreens in a cosmetic acceptable carrier a combination of at least two special lipophilic filters included, with one filter solubilizing over the other filter Possesses properties. The invention further relates to a method for solubilizing one or two special solid lipophilic Filter in one or two types of special liquid lipophilic Filter.

It is known to be due to light radiation with a wavelength in the range from 280 to 400 nm the human epidermis are tanned can and that radiation with a wavelength in the range of 280 to 320 nm, which is known as UV-B, erythema and Skin burns that cause the formation of natural tan detrimental could be; UV-B radiation should therefore be filtered out.

It it is also known that UV-A radiation with a wavelength in the range from 320 to 400 nm, which tans the skin, a change the skin can cause, especially in the case of sensitive Skin or skin that is continuously exposed to sunlight. UV-A radiation leads in particular cause the skin to become elastic loses and wrinkles occur, leading to premature aging leads. It favors triggering erythema formation or increased this reaction in some people, and it can even be the cause for through Light triggered toxic or allergic reactions. It is therefore desirable, too filter out the UV-A radiation.

To now numerous cosmetic compositions have been used for sun protection (UV-A and / or UV-B) of the skin proposed.

Out various reasons which are particularly easy to use (softness, smoothness, ease of use, etc.), there are sunscreens currently mostly in the form of an oil-in-water type emulsion (i.e. one cosmetically acceptable carrier, that of a continuous dispersing aqueous phase and a discontinuous dispersed oil phase exists), which in different concentrations one or more conventional contains organic filters, which the harmful UV radiation selective can absorb where the filters depend of the desired sun protection factor selected (the sun protection factor (LS) is mathematically called the ratio of the Irradiation time, which is necessary to reduce the erythema threshold dose to achieve with the UV filter at the time that is necessary to to reach the erythema threshold dose without a UV filter, expressed). Corresponding their lipophilic or hydrophilic properties can Filters either in the fat phase or in the aqueous phase of the finished one Composition.

It has been found to be lipophilic organic UV filters that cosmetically particularly interesting and in the UV-A range and UV-B range are highly effective in the patent applications EP-A-0 392 883, EP-A-0 660 701, EP-A-0 708 108, EP-A-0 711 778 and EP-A-711 779 were. They are silanes or polyorganosiloxanes with a benzotriazole group. These connections have the peculiarity, but also the disadvantage, that they are solid at room temperature. This is their use in a cosmetic sunscreen composition with certain limitations in terms of associated with their formulation and their application, in particular, when it comes to solvents specify that they can solubilize properly. Today oils are mostly used for this, such as esters and especially alkyl benzoates having 12 to 15 carbon atoms ("FINSOLV TN" from Finetex), triglycerides and especially triglycerides of fatty acids with 8 to 12 carbon atoms ("MIGLYOL 812" from Hüls) or also monoalcohols or polyols such as ethanol and mixtures thereof. Although these products have solubilizing properties over the have the above filters, they still have the disadvantage on, no own activity for Filtering out both UV-A and UV-B radiation.

The applicant has now unexpectedly and surprisingly found that UV filters of the cinnamic acid derivative type and / or UV filter of the salicylic acid derivative type are particularly remarkable solvents for the above-mentioned solid filters, ie for silicon-containing derivatives with a benzotriazole group. It should be pointed out that cinnamic acid derivatives and salicylic acid derivatives are liquid lipophilic filters which are known per se for their effectiveness in the UV-B range, but whose solubilizing properties have not yet been described for the filters specified above. The present finding is therefore in interesting in two respects, since it is now possible, on the one hand, to carry out the solubilization of a silicon-containing derivative having a benzotriazole group or a mixture of such compounds with a solvent which is different from the solvents known in the prior art, which is in itself interesting, and on the other hand to Increase the amount of the filters and increase a substantial amount of the filters and achieve a substantial increase in the protective effect associated with the filters in the finished light protection composition.

This Findings are the basis of the present invention.
